On May 24 Panasonic performed a robotic publicity stunt to promote Evolta. Specifically the stunt was to demonstrate the endurance of the AA alkaline dry-cell batteries.
The stunt had a 17-centimeter tall, 130-gram Panasonic Robot powered by a pair Evolta batteries scale a 500-meter cliff at the Grand Canyon.
During the 6 hour and 45 minute stunt, which the Guinness Book of World Records recognized as the longest-lasting of its kind, the robot hoisted itself up a 530-meter length of rope suspended next to the cliff.
Energizer, bring up your bunnies, I smell a robotic duel!
